The biggest problem is with the commercial hosting services, which tend to like to
provide download links that cannot be used to download the file
directly: they instead show a page which performs a redirect to the actual data
file, or, worse, to a page full of adverts in which the user much click
a further button to get the download. These shenanigans rather undermine
my attempts to allow Texturejam to rely on their existing hosting.

On the other hand Texturecraft provides a straightforward download
link direct to the ZIP file, which for my purposes is ideal.

I have also been having an exasperating time creating examples of the
Beta-1.3 upgrade—often I fight Mediafire for a copy of the texture pack,
do the upgrades, test the pack, go to the forums to post a link to it,
and discover that there was a newer version of the pack on a different
texture-pack-hosting service that makes the whole exercise redundant.
Grr. I am beginning to think that finding a way to disentangle this mess
might be a useful service in its own right.
